传染性法氏囊病病毒的生态学研究——非鸡禽鸟类自然感染传染性法氏囊病病毒的血清学调查

Study on the ecology of infectious bursal disease virus(IBDV): serological surveys on non chicken avian species for natural infections by IBDV

用传染性法氏囊病病毒（ＩＢＤＶ）单克隆抗体夹心阻断ＥＬＩＳＡ对麻雀、鸭、鹅进行了ＩＢＤＶ血清学调查，麻雀的阳性率为７．４％（４／５４），鸭的阳性率为９５．５％（３６３／３８０），鹅的阳性率为９．４％（１１／１１７）。表明ＩＢＤＶ传播已非常广泛，提示麻雀、鸭、鹅特别是鸭在ＩＢＤＶ生态和传播中可能起重要作用。

Using the anti IBDV monoclonal antibody-sandwich block ELISA,sparrows(n=54),ducks(n=380) and geese(n=117) collected from different regions in our country were serologically examined for IBDV infections.It is shown that the IBDV infection positive rate is 7.4% in sparrows,95.5% in ducks and 9.4% in geese respectively which indicates that the prevalence of IBDV is very extensive in our country and which reveals that sparrows,ducks and geese especially ducks may play an important role in both the ecology and the transmission of IBDV.
